Source Code Review
— SaaS & Technology
Proof-driven Source Code Review for organizations in SaaS & Technology. We deliver validated exploit evidence, not automated scanner noise.
Free Scoping CallSaaS & Technology Vulnerability Intelligence
SaaS platforms serve as critical infrastructure for thousands of businesses. A single tenant isolation failure can cascade into a multi-organization data breach affecting millions of end users.
Multi-Tenant Data Isolation Failures
Insufficient tenant boundary enforcement in shared infrastructure allowing cross-tenant data access, configuration leakage, and privilege escalation between customer environments.
OAuth/OIDC Implementation Flaws
Misconfigured OAuth flows enabling token theft, redirect URI manipulation, scope escalation, and authorization code interception in SSO integrations.
GraphQL Query Depth and Batching Exploits
Unrestricted GraphQL query complexity allowing denial-of-service through deeply nested queries, field suggestion enumeration, and batch query abuse for data exfiltration.
CI/CD Pipeline Poisoning
Compromised build pipelines enabling supply-chain attacks through malicious dependency injection, pipeline variable manipulation, and artifact tampering.
Attack Surface
- Tenant management APIs
- Authentication and SSO
- GraphQL/REST APIs
- CI/CD pipelines
- Webhook integrations
- Admin consoles
